Understanding the Long-Short Ratio
The Long-Short Ratio is a sentiment analysis metric that gauges the relative strength of bullish vs. bearish trends in a market. This ratio compares:
- Long positions (traders expecting price increases)
- Short positions (traders expecting price decreases)
Key Interpretation:
- Ratio > 1: More long positions → Bullish sentiment
- Ratio < 1: More short positions → Bearish sentiment
Calculation Method
Long-Short Ratio = Total Long Positions / Total Short PositionsExample: 80 long positions ÷ 40 short positions = Ratio of 2.0

Critical Clarifications

- High ratio (e.g., 1.5): More traders hold longs → Likely retail-dominated
- Low ratio: Fewer traders hold shorts → Often institutional activity

Practical Implications
- Extreme ratios signal potential reversals
When retail traders overcrowd one side (e.g., excessive longs), institutional players may force liquidations through price movements. - Limitations exist
Arbitrage strategies (cross-exchange hedging, funding rate plays) can distort raw ratio data.

Strategic Insights
- Watch whale ratios
When大户 (whales) positions contradict retail sentiment, prepare for potential volatility. - Combine with other indicators
Ratios alone don't predict price - confirm with order book depth, funding rates, and macroeconomic factors. - Historical context matters
Bitcoin's "normal" ratio ranges 1.0–1.2. Extreme readings (>1.5 or <0.8) warrant caution.
